Ecclesiastes 11:5-7 Revised Standard Version Catholic Edition (RSVCE)
5 As you do not know how the spirit comes to the bones in the womb[a] of a woman with child, so you do not know the work of God who makes everything.
6 In the morning sow your seed, and at evening withhold not your hand; for you do not know which will prosper, this or that, or whether both alike will be good.

7 Light is sweet, and it is pleasant for the eyes to behold the sun.
